The receptaclc A is also provided with a plugU in. the bottom thereof, which may be re-- moved for draining out themuddy water whenever necessary.

What I claim as my invention is 1. In an air-washenithe combination witha receptacle containing the washing liquid of air inlet and outletconnections to said receptacle, a float for supporting the air inletconnection and for maintaining the same in constant relation to thelevel of the li uid, and means operated by said float for s utting offthe air when the liquid has dropped to a predetermined level.

2. In an air-washer, the combination with a receptaclecontaining thewashing fluid, of air inlet and outlet connections to said receptacle, afloat for supporting the air inlet connection and automaticallymaintaining a constant relation between the same and the level of theliquid, and means carried by said air inlet connection for cuttin offthe air when lowered to a predetermined point.

3. In an air-washer, the combination with a receptacle containing thewashing fluid, of a float within said receptacle, an air inlet tubecarried by said float and having its discharge end maintained inconstant relation to the level of the water, a hood carried by saidinlet, and a seat cooperating with said hood to close the inlet when thelevel of the liquid drops to a predetermined point.

4i. In an air-washer, the combination with a receptacle containing thewashing fluid, of air inlet and outlet connections, a float foradjustably supporting the air inlet connection and maintaining aconstant relation bean auxiliary tween the same and the level of the liuid,

means operating upon the drop ing 0 the 4 5 liquid level to a*predetermine point for cutting off the supplypf air, and auxiliarymeans for supplying an.

the liquid, means for automatically cuttin ofl the air supply when the'liquid leve drops to a predetermined oint, a filler for the liquid, anda removahle cap for said filler permitting the use of the same as anauxiliary air inlet when the liquid is exhausted.

6. In an air-washer, the combination with a receptacle containin in thelower portion thereof the washing uid, of air inlet and outletconnections, for said receptacle, a float for adjustably supporting theair inlet connection and maintaining the same in constant relation tothe level of the liquid, means for automatically cutting off the airsupply when the liquid level drops to a predetermined point, means forseparating the liquid from the air located in said receptacle above theliquid level, a filler for the liquid located to limit the level ofliquid introduced therethrough to below said separating means, and aremovable closure for said filler permitting the useof the same as airinlet when the normal air inlet is cut off.

In testimoniy whereof I aifix my signature in presence 0 two witnesses.
